Title: Interface for a high performance low cost video game system with coprocessor providing high speed efficient 3D graphics and digital audio signal processing

Abstract: A low cost high performance three dimensional (3D) graphics system is disclosed that can model a world in three dimensions and project the model onto a two dimensional viewing plane selected based on a changeable viewpoint. The viewpoint can be changed on an interactive, real time basis by operating user input controls such as game controllers. The system rapidly produces a corresponding changing image (which can include animated cartoon characters or other animation) on the screen of a color television set. The richly featured high performance low cost system is intended to give consumers the chance to interact in real time right inside magnificent virtual 3D worlds to provide a high degree of image realism, excitement and flexibility. An optimum feature set/architecture (including a custom designed graphics/audio coprocessor) provides high quality fast moving 3D images and digital stereo sound for video game play and other graphics applications. Numerous features provide flexibility and capabilities in a system that is intended to be within the cost range of most consumers.
